Search for a resonance decaying into WZ boson Pairs in pp̄ collisions
2010
We present the first search for an
electrically chargedresonance W' decaying to a WZ boson pair using 4.1 fb(-1) of integrated luminosity collected with the D0 detector at the
Fermilab
Tevatronp (p) over bar collider. The WZ pairs are reconstructed through their decays into three charged leptons (l = e, mu). A total of 9 data events is observed in good agreement with the background prediction. We set 95% C.L. limits on the W'WZ coupling and on the W' production cross section multiplied by the
branching fractions. We also exclude W' masses between 188 and 520 GeV within a
simple extensionof the standard model and set the most restrictive limits to date on low-scale
technicolormodels.
